Abstract
For a reliable identification of noise sources generating noise or sound signals, according to the invention, in a method for determining a noise signal (S) of a noise source (10), the noise signal (S) is detected and analyzed on the basis of signal properties, the noise signal (S) being compared with noise patterns (M) and being assigned to a noise source type (T) on the basis of the comparison.
